2. Description of the Related Art

Pattern formation is the activity by which embryonic cells form orderedspatial arrangements of differentiated tissues. Speculation on themechanisms underlying these patterning effects usually centers on thesecretion of a signaling molecule that elicits an appropriate responsefrom the tissues being patterned. More recent work aimed at theidentification of such signaling molecules implicates secreted proteinsencoded by individual members of a small number of gene families.

A longstanding idea in cancer biology is that cancers arise and grow dueto the formation of cancer stem cells, which may constitute only aminority of the cells within a tumor but are nevertheless critical forits propagation. Stem cells are appealing as the cell of origin forcancer because of their pre-existing capacity for self-renewal and forunlimited replication. In addition, stem cells are relatively long-livedin comparison to other cells within tissues, providing a greateropportunity to accumulate the multiple additional mutations that may berequired to increase the rate of cell proliferation and produceclinically significant cancers. Of particular recent interest in theorigin of cancer is the observation that the Wnt signaling pathway,which has been implicated in stem cell self-renewal in normal tissues,upon continuous activation has also been associated with the initiationand growth of many types of cancer. This pathway thus provides apotential link between the normal self-renewal of stem cells and theaberrantly regulated proliferation of cancer stem cells.

The Wnt growth factor family includes more than 10 genes identified inthe mouse and at least 7 genes identified in the human. Members of theWnt family of signaling molecules mediate many important short- andlong-range patterning processes during invertebrate and vertebratedevelopment. The Wnt signaling pathway is known for its important rolein the inductive interactions that regulate growth and differentiation,and likely also plays important roles in the homeostatic maintenance ofpost-embryonic tissue integrity. Wnt stabilizes cytoplasmic p-catenin,which stimulates the expression of genes including c-myc, c jun, fra-1,and cyclin D1. In addition, misregulation of Wnt signaling can causedevelopmental defects and is implicated in the genesis of several humancancers. More recently, the Wnt pathway has been implicated in themaintenance of stem or progenitor cells in a growing list of adulttissues that now includes skin, blood, gut, prostate, muscle and thenervous system.

Pathological activation of the Wnt pathway is also believed to be theinitial event leading to colorectal cancer in over 85% of all sporadiccases in the Western world. Activation of the Wnt pathway has also beenextensively reported for hepatocellular carcinoma, breast cancer,ovarian cancer, pancreatic cancer, melanomas, mesotheliomas, lymphomasand leukemias. In addition to cancer, inhibitors of the Wnt pathway canbe used for stem cell research or for the treatment of any diseasescharacterized by aberrant Wnt activation such as diabetic retinopathy,pulmonary fibrosis, rheumatoid arthritis, scleroderma as well as mycoticand viral infections and bone and cartilage diseases. As such, it is atherapeutic target that is of great interest to the field.

In addition to cancer, there are many cases of genetic diseases due tomutations in Wnt signaling components. Examples of some of the manydiseases are Alzheimer's disease [Proc. Natl. Acad. Sci. USA (2007),104(22), 9434-9], osteoarthritis, polyposis coli [Science (1991),253(5020), 665-669], bone density and vascular defects in the eye(osteoporosis-pseudoglioma syndrome, OPPG) [N. Engl. J.

Regulation of cell signaling by the Wnt signaling pathway is criticalfor the formation of neuronal circuits. Wnt pathway modulates in neuraltissue, among other things, axon pathfinding, dendritic development, andsynaptic assembly. Through different receptors, Wnt pathway activatesand/or regulates diverse signaling pathways and other processes thatlead to local changes on the cytoskeleton or global cellular changesinvolving nuclear function. Recently, a link between neuronal activity,essential for the formation and refinement of neuronal connections, andWnt signaling has been uncovered. Indeed, neuronal activity regulatesthe release of various Wnt proteins and the localization of theirreceptors. Wnt pathway mediates synaptic structural changes induced byneuronal activity or experience. Evidence suggests that dysfunction inWnt signaling contributes to neurological disorders [Brain ResearchReviews (2000), 33(1), 1-12; Oncogene (2006) 25(57), 7545-7553;Molecular Neurodegeneration (2008), 3, 9; Neurobiology of Disease(2010), 38(2), 148-153; Journal of Neurodevelopmental Disorders (2011),3(2), 162-174 and Cold Spring Harbor Perspectives in Biology February(2012), 4(2)].

Synergy, as described, for example, by Chou, CancerResearch (2010), 70(2), 440-446, occurs when the effect of the compoundswhen administered in combination is greater than the additive effect ofthe compounds when administered alone as a single agent. In general, asynergistic effect is most clearly demonstrated at sub-optimalconcentrations of the compounds. It will be appreciated that differentconcentrations may be employed for prophylaxis than for treatment of anactive disease. This amount can further depend upon the patient'sheight, weight, sex, age and medical history.

A therapeutic effect relieves, to some extent, one or more of thesymptoms of the disease, and includes curing a disease. “Curing” meansthat the symptoms of active disease are eliminated. However, certainlong-term or permanent effects of the disease may exist even after acure is obtained (such as extensive tissue damage).

“Treat,” “treatment,” or “treating,” as used herein refers toadministering a compound or pharmaceutical composition as providedherein for therapeutic purposes. The term “therapeutic treatment” refersto administering treatment to a patient already suffering from a diseasethus causing a therapeutically beneficial effect, such as amelioratingexisting symptoms, preventing additional symptoms, ameliorating orpreventing the underlying metabolic causes of symptoms, postponing orpreventing the further development of a disorder and/or reducing theseverity of symptoms that will or are expected to develop.

“Drug-eluting” and or controlled release as used herein refers to anyand all mechanisms, e.g., diffusion, migration, permeation, and/ordesorption by which the drug(s) incorporated in the drug-elutingmaterial pass therefrom over time into the surrounding body tissue.

“Drug-eluting material” and or controlled release material as usedherein refers to any natural, synthetic or semi-synthetic materialcapable of acquiring and retaining a desired shape or configuration andinto which one or more drugs can be incorporated and from whichincorporated drug(s) are capable of eluting over time.

“Elutable drug” as used herein refers to any drug or combination ofdrugs having the ability to pass over time from the drug-elutingmaterial in which it is incorporated into the surrounding areas of thebody.

For optimal delivery to thelung, inhaled aerodynamic particle sizes of about less than 10 μm areuseful, with an aerodynamic particle size of about 1 to about 10 micronsbeing preferred Inhaled particles may be defined as liquid dropletscontaining dissolved drug, liquid droplets containing suspended drugparticles (in cases where the drug is insoluble in the suspendingmedium), dry particles of pure drug substance, drug substanceincorporated with excipients, liposomes, emulsions, colloidal systems,coacervates, aggregates of drug nanoparticles, or dry particles of adiluent which contain embedded drug nanoparticles.

In some embodiments, compounds of Formula (I) disclosed herein intendedfor respiratory delivery (either systemic or local) can be administeredas aqueous formulations, as non-aqueous solutions or suspensions, assuspensions or solutions in halogenated hydrocarbon propellants with orwithout alcohol, as a colloidal system, as emulsions, coacervates or asdry powders. Aqueous formulations may be aerosolized by liquidnebulizers employing either hydraulic or ultrasonic atomization or bymodified micropump systems (like the soft mist inhalers, the Aerodose®or the AERx® systems). Propellant-based systems may use suitablepressurized metered-dose inhalers (pMDIs). Dry powders may use drypowder inhaler devices (DPIs), which are capable of dispersing the drugsubstance effectively. A desired particle size and distribution may beobtained by choosing an appropriate device.

In some embodiments, the compositions of Formula (I) disclosed hereincan be administered to the ear by various methods. For example, a roundwindow catheter (e.g., U.S. Pat. Nos. 6,440,102 and 6,648,873) can beused.

Alternatively, formulations can be incorporated into a wick for usebetween the outer and middle ear (e.g., U.S. Pat. No. 6,120,484) orabsorbed to collagen sponge or other solid support (e.g., U.S. Pat. No.4,164,559).

If desired, formulations of the invention can be incorporated into a gelformulation (e.g., U.S. Pat. Nos. 4,474,752 and 6,911,211).

In some embodiments, compounds of Formula (I) disclosed herein intendedfor delivery to the ear can be administered via an implanted pump anddelivery system through a needle directly into the middle or inner ear(cochlea) or through a cochlear implant stylet electrode channel oralternative prepared drug delivery channel such as but not limited to aneedle through temporal bone into the cochlea.

Other options include delivery via a pump through a thin film coatedonto a multichannel electrode or electrode with a specially imbeddeddrug delivery channel (pathways) carved into the thin film for thispurpose. In other embodiments the acidic or basic solid compound ofFormula I can be delivered from the reservoir of an external or internalimplanted pumping system.

Formulations of the invention also can be administered to the ear byintratympanic injection into the middle ear, inner ear, or cochlea(e.g., U.S. Pat. No. 6,377,849 and Ser. No. 11/337,815).

Intratympanic injection of therapeutic agents is the technique ofinjecting a therapeutic agent behind the tympanic membrane into themiddle and/or inner ear. In one embodiment, the formulations describedherein are administered directly onto the round window membrane viatranstympanic injection. In another embodiment, the ion channelmodulating agent auris-acceptable formulations described herein areadministered onto the round window membrane via a non-transtympanicapproach to the inner ear. In additional embodiments, the formulationdescribed herein is administered onto the round window membrane via asurgical approach to the round window membrane comprising modificationof the crista fenestrae cochleae.

In some embodiments, the compounds of Formula (I) are formulated inrectal compositions such as enemas, rectal gels, rectal foams, rectalaerosols, suppositories, jelly suppositories, or retention enemas,containing conventional suppository bases such as cocoa butter or otherglycerides, as well as synthetic polymers such as polyvinylpyrrolidone,PEG (like PEG ointments), and the like.

Suppositories for rectal administration of the drug (either as asolution, colloid, suspension or a complex) can be prepared by mixingthe drug with a suitable non-irritating excipient that is solid atordinary temperatures but liquid at the rectal temperature and willtherefore melt or erode/dissolve in the rectum and release the drug.Such materials include cocoa butter, glycerinated gelatin, hydrogenatedvegetable oils, poloxamers, mixtures of polyethylene glycols of variousmolecular weights and fatty acid esters of polyethylene glycol. Insuppository forms of the compositions, a low-melting wax such as, butnot limited to, a mixture of fatty acid glycerides, optionally incombination with cocoa butter is first melted.

Solid compositions can be provided in various different types of dosageforms, depending on the physicochemical properties of the drug, thedesired dissolution rate, cost considerations, and other criteria. Inone of the embodiments, the solid composition is a single unit. Thisimplies that one unit dose of the drug is comprised in a single,physically shaped solid form or article. In other words, the solidcomposition is coherent, which is in contrast to a multiple unit dosageform, in which the units are incoherent.

Examples of single units which may be used as dosage forms for the solidcomposition include tablets, such as compressed tablets, film-likeunits, foil-like units, wafers, lyophilized matrix units, and the like.In a preferred embodiment, the solid composition is a highly porouslyophilized form. Such lyophilizates, sometimes also called wafers orlyophilized tablets, are particularly useful for their rapiddisintegration, which also enables the rapid dissolution of the activecompound.

On the other hand, for some applications the solid composition may alsobe formed as a multiple unit dosage form as defined above. Examples ofmultiple units are powders, granules, microparticles, pellets,mini-tablets, beads, lyophilized powders, and the like. In oneembodiment, the solid composition is a lyophilized powder. Such adispersed lyophilized system comprises a multitude of powder particles,and due to the lyophilization process used in the formation of thepowder, each particle has an irregular, porous microstructure throughwhich the powder is capable of absorbing water very rapidly, resultingin quick dissolution. Effervescent compositions are also contemplated toaid the quick dispersion and absorption of the compound.

Another type of multiparticulate system which is also capable ofachieving rapid drug dissolution is that of powders, granules, orpellets from water-soluble excipients which are coated with the drug, sothat the drug is located at the outer surface of the individualparticles. In this type of system, the water-soluble low molecularweight excipient is useful for preparing the cores of such coatedparticles, which can be subsequently coated with a coating compositioncomprising the drug and, preferably, one or more additional excipients,such as a binder, a pore former, a saccharide, a sugar alcohol, afilm-forming polymer, a plasticizer, or other excipients used inpharmaceutical coating compositions.

Also provided herein are kits. Typically, a kit includes one or morecompounds or compositions as described herein. In certain embodiments, akit can include one or more delivery systems, e.g., for delivering oradministering a compound as provided herein, and directions for use ofthe kit (e.g., instructions for treating a patient). In anotherembodiment, the kit can include a compound or composition as describedherein and a label that indicates that the contents are to beadministered to a patient with cancer. In another embodiment, the kitcan include a compound or composition as described herein and a labelthat indicates that the contents are to be administered to a patientwith one or more of hepatocellular carcinoma, colon cancer, leukemia,lymphoma, sarcoma, ovarian cancer, diabetic retinopathy, pulmonaryfibrosis, rheumatoid arthritis, scleroderma, mycotic and viralinfections, bone and cartilage diseases, Alzheimer's disease, lungdisease, osteoarthritis, polyposis coli, bone density and vasculardefects in the eye (Osteoporosis-pseudoglioma Syndrome, OPPG), familialexudative vitreoretinopathy, retinal angiogenesis, early coronarydisease, tetra-amelia, Müllerian-duct regression and virilization,SERKAL syndrome, type II diabetes, Fuhrmann syndrome,Al-Awadi/Raas-Rothschild/Schinzel phocomelia syndrome,odonto-onycho-dermal dysplasia, obesity, split-hand/foot malformation,caudal duplication, tooth agenesis, Wilms tumor, skeletal dysplasia,focal dermal hypoplasia, autosomal recessive anonychia, neural tubedefects, alpha-thalassemia (ATRX) syndrome, fragile X syndrome, ICFsyndrome, Angelman's syndrome, Prader-Willi syndrome, Beckwith-WiedemannSyndrome, Norrie disease and Rett syndrome. The actual dose of theactive compounds of the present invention depends on the specificcompound, and on the condition to be treated; the selection of theappropriate dose is well within the knowledge of the skilled artisan.

Evaluation of Biological Activity

The biological activity of the compounds described herein can be testedusing any suitable assay known to those of skill in the art, e.g., WO2001/053268 or WO 2005/009997. For example, the activity of a compoundmay be tested using one or more of the test methods outlined below.

In one example, tumor cells may be screened for Wnt independent growth.In such a method, tumor cells of interest are contacted with a compound(i.e. inhibitor) of interest, and the proliferation of the cells, e.g.by uptake of tritiated thymidine, is monitored. In some embodiments,tumor cells may be isolated from a candidate patient who has beenscreened for the presence of a cancer that is associated with a mutationin the Wnt signaling pathway. Candidate cancers include, withoutlimitation, those listed above.

In another example, one may utilize in vitro assays for Wnt biologicalactivity, e.g. stabilization of β-catenin and promoting growth of stemcells. Assays for biological activity of Wnt include stabilization ofβ-catenin, which can be measured, for example, by serial dilutions of acandidate inhibitor composition. An exemplary assay for Wnt biologicalactivity contacts a Wnt composition in the presence of a candidateinhibitor with cells, e.g. mouse L cells. The cells are cultured for aperiod of time sufficient to stabilize β-catenin, usually at least about1 hour, and lysed. The cell lysate is resolved by SDS PAGE, thentransferred to nitrocellulose and probed with antibodies specific forβ-catenin.

In a further example, the activity of a candidate compound can bemeasured in a Xenopus secondary axis bioassay (Leyns, L. et al. Cell(1997), 88(6), 747-756).

Final deprotection of the pyrazolenitrogen yields the desired indazole derivatives (VIII).

Alternatively, compounds of Formula I of the present invention can beprepared as depicted in Scheme 2.

Scheme 2 describes an alternative method for preparation of indazolederivatives (VIII) by first formylating 5-bromo-1H-indole (IX) toproduce 5-bromo-1H-indazole-3-carbaldehyde (X) followed by protectionwith either SEM-Cl or DHP to give the protected aldehyde (XI). Aldehyde(XI) is then reacted with bis(pinacolato)diboron to form the borateester (XII). Suzuki coupling with various bromides (IV) yields indazolederivatives (XIII). Aldehyde (XIII) is reacted with various 1,2-diamines(VI) to produce (XIV). Final deprotection of the pyrazole nitrogenyields the desired indazole derivatives (VIII).

The reaction was heated to60-65° C. for two hours and then allowed to cool to room temperature.N,O-Dimethylhydroxylamine-HCl (66.2 g, 678 mmol) was added as a solidand the mixture was heated to 65° C. for 3 hours. The reaction wasconcentrated to a paste and taken up in DCM, and washed subsequentlywith water and 2N HCl. The product could be seen coming out of solution.The solid was filtered and rinsed separately with EtOAc. The EtOAc andDCM layers were separately washed with sodium bicarbonate followed bybrine, dried over MgSO4 and concentrated under reduced pressure. Theresulting solids were combined, triturated with 1:1 mixture ofDCM-ether, filtered, and dried to produceN-methoxy-N-methyl-1H-indazole-3-carboxamide (XVI) as a white solid (100g, 487 mmol, 79% yield). ¹H NMR (DMSO-d₆) δ ppm 3.46 (s, 3H), 3.69-3.85(m, 3H), 7.13-7.31 (m, 1H), 7.41 (t, J=7.25 Hz, 1H), 7.56-7.65 (m, 1H),7.93-8.08 (m, 1H); ESIMS found for C₁₀H₁₁N₃O₂ m/z 206 (M+H).

Step 2

To the N-methoxy-N-methyl-1H-indazole-3-carboxamide (XVI) (20 g, 97.4mmol) in DCM (1 L) was added bis(trifluoroacetoxy)iodobenzene (46 g, 107mmol) followed by portionwise addition of iodine (14.84 g, 58.5 mmol) atroom temperature.

Example 2

The above synthesized compounds were screened using the assay procedurefor Wnt activity described below.

Reporter cell lines can be generated by stably transducing cells ofcancer cell lines (e.g., colon cancer) with a lentiviral construct thatinclude a wnt-responsive promoter driving expression of the fireflyluciferase gene.

Lentiviral constructs can be made in which the SP5 promoter, a promoterhaving eight TCF/LEF binding sites derived from the SP5 promoter, islinked upstream of the firefly luciferase gene. The lentiviralconstructs can also include a hygromycin resistance gene as a selectablemarker. The SP5 promoter construct can be used to transduce SW480 cells,a colon cancer cell line having a mutated APC gene that generates atruncated APC protein, leading to de-regulated accumulation ofβ-catenin. A control cell line can be generated using another lentiviralconstruct containing the luciferase gene under the control of the SV40promoter which does not require β-catenin for activation.

Cultured SW480 cells bearing a reporter construct can be distributed atapproximately 10,000 cells per well into 384 well multiwell plates.Compounds from a small molecule compound library can then be added tothe wells in half-log dilutions using a three micromolar topconcentration. A series of control wells for each cell type receive onlybuffer and compound solvent. Twenty-four hours after the addition ofcompound, reporter activity for luciferases can be assayed, for example,by addition of the BrightGlo luminescence reagent (Promega) and theVictor3 plate reader (Perkin Elmer). Readings can be normalized to DMSOonly treated cells, and normalized activities can then be used in theIC₅₀ calculations. Table 2 shows the activity of selected indazoleanalogs.

Preparation of a 220 μg/mL suspension in 0.5% CMC/0.05% tween 80 beginsby dispensing 597 g±1 g of Gibco 1×PBS into the 1 L glass bottle. Usinga 1 mL sterile syringe, measure 0.3 mL of Tween 80. In a weigh boat,weigh out 3 g±0.1 g of Carboxymethyl Cellulose 7LXF PH (CMC). Startmixing the Tween80/PBS solution and slowly sprinkle the CMC into the 1 Lbottle containing the PBS/Tween mixture (increase mixing speed asnecessary). Once visually dispersed and the polymer is hydrated, startheating the container on a heating plate to promote phase inversion(turbidity). Once the solution is cool to the touch, filter NLT 120 mLinto the 250 mL glass bottle. Weigh 27 mg of a compound of Formula I andsuspend by mixing with the aid of 120 g of the sterile filteredCMC/tween solution. Fill 2 mL schott glass vials and 13 mm Fluroteccoated stoppers (West Pharma) and autoclave the vials at 260° F. for NLT25 minutes. Particle size measurement (Table 4) was performed afterautoclaving using a Horiba L-950.
